Es sind sowohl Fräser zur Herstellung von Zahnrädern bekannt geworden, bei denen der eigentliche Fräserkörper von einzelnen Messern gebildet wird, als auch solche Fräser, bei denen diese Messer einstellbar sind. Diese Fräser sind Jedoch außerordentlich teuer; es sind namentlich einstellbare Fräser einem hohen Verschleiß unterworfen, so daß sie für die Praxis wenig Wert besitzen.There are both milling cutters for the production of gears are known in which the actual cutter body is formed by individual knives, as well as such cutters which these knives are adjustable. However, these milling cutters are extremely expensive; it Namely adjustable milling cutters are subject to high wear, so that they are suitable for practice have little value.
Diese Nachteile sollen durch den Gegenstand der Erfindung beseitigt werden, bei welchem der eigentliche Fräser aus einem geschlitzten Kreissägeblatt (Schlitz- oder Scheibenfräser) besteht, daa entsprechend der Steigung der zu bearbeitenden Schnecke durch auswechselbare Backen verspannt werden kann.These disadvantages are intended to be eliminated by the subject matter of the invention, in which the actual milling cutter from a slotted circular saw blade (slot or disk milling cutter) consists, daa according to the pitch of the worm to be machined by replaceable Jaws can be clamped.
Dieser Fräser stellt sich in der Herstellung außerordentlich billig, da er nur aus drei Tei-, len besteht, außerdem können mit diesem Fräser selbst kleinste Schnecken schnell bearbeitet werden, was mit anderen verstellbaren Fräsern bisher nicht möglich war, da mit RücksichtThis milling cutter is extremely cheap to manufacture because it only consists of three parts, len, and even the smallest worms can be machined quickly with this milling cutter what was previously not possible with other adjustable milling cutters, because with consideration
auf die Verstellbarkeit die einzelnen Messer ziemlich stark gehalten werden mußten, um
der auftretenden starken Beanspruchung beim Fräsen« Rechnung zu tragen.
In der Zeichnung 1st ein Ausführungsbeispiel des Fräsers dargestellt, und zwar zeigt
Abb. ι den Scheibenfräser und
Abb. 2 denselben durch Spannbacken entsprechend der Steigung der zu fräsendenthe adjustability of the individual knives had to be kept fairly strong in order to take into account the heavy loads that occur during milling.
In the drawing, an embodiment of the milling cutter is shown, namely shows
Fig. Ι the side milling cutter and
Fig. 2 the same by clamping jaws according to the slope of the to be milled
to Schnecke verspannt.to snail braced.
Der Scheibenfräser, z.B. ein Sägeblatt i, besitzt eine Bohrung 2, von der aus bis zum äußeren Umfange sich ein Schlitz 3 erstreckt. Naturgemäß kann der radiale Schlitz 3 auchThe side milling cutter, e.g. a saw blade i, has a hole 2 from which to the outer circumference a slot 3 extends. Of course, the radial slot 3 can also
tangential zur Bohrung 2 verlaufen oder in einer Kurve. Um diesem Scheibenfräser die Steigung der Schnecke zu geben, sind Backen 4 und 5 vorgesehen, welche entsprechend der Steigung der zu fräsenden Schnecke schrau-run tangentially to hole 2 or in a curve. To this side milling cutter the To give the screw pitch, jaws 4 and 5 are provided, which correspond to the Pitch of the worm to be milled
ao benförmig verlaufende Flächen 6 besitzen, die sich beim Aufbringen des Fräsers auf den Fräsdorn gegen den Scheibenfräser 1 legen und somit das Verspannen entsprechend der Steigung der Schnecke bewirken.ao have beniform running surfaces 6, which when the cutter is applied to the Place the milling arbor against the side milling cutter 1 and thus the clamping according to the Cause the screw to slope.
Selbstverständlich könnte man auch bei stärkeren Scheibenfräsern eine vollkommene Teilung des Fräsers in zwei oder mehrere Kreisausschnitte vornehmen, wie dies in Abb. ι strichpunktiert angedeutet ist.It goes without saying that a perfect one could also be used with stronger side milling cutters Divide the milling cutter into two or more circular sections, as shown in Fig. Ι is indicated by dash-dotted lines.
